| Abstract | A study is conducted to reduce the overall cost of pile foundations. The best shape and optimal spacing for different capacity requirements are
probed for, in a large variety of piles commonly used in Bangkok. Group capacity concept and block failure criterion along with a cost function are used to evaluate the cost incurred in transferring one tonne of load from the superstructure to the soil stratum below, denoted as 1unit cost' which is used for comparisons. Optimal choice based on pile types and overall optimal choice are tabulated along with graphical presentation of group capacity - unit cost relationships. A step by step procedure is presented to use the system model developed, for practical applications,
Footings from the proposed model are compared with the footing designs from Thailand Tobacco Monopoly and are found to be highly competitive.
Pile groups with more than 9 piles and groups with pile length less than 12 metres used to support footing loads exceeding 20 tonnes are found to be uneconomical. Piles with smaller lateral dimensions tend to be more economical. As the unit cost increases with footing capacity, the results from this study advocate the use of smaller footings, if the designs permit. |
